Search found Beebo as an announced/under-assessment hybrid project, not an operating registered DUID. Official EPBC material identifies the project as a 600 MW solar farm plus standalone 400 MW/800 MWh BESS near Texas/Goondiwindi, Queensland. The user-supplied 600 MW capacity appears to refer to the solar farm; battery financial assumptions here are modelled for the official 400 MW/800 MWh 2-hour BESS. No project-specific capex, financing, O&M contract, battery OEM, tolling/offtake, or augmentation contract was found. Capex is a default/benchmark estimate derived from the 2025 GHD/AEMO large-scale lithium-ion BESS assumptions for a co-located 2-hour BESS: AUD 369/kW power component plus AUD 290/kWh energy component, scaled to 400 MW/800 MWh, plus one AUD 10 million land/development allowance. Fixed opex uses the GHD/AEMO 2-hour BESS total annual O&M assumption including extended warranty: AUD 10,000/MW-year fixed O&M plus AUD 5,000/MW-year extended warranty. Variable O&M is treated as AUD 0/MWh because GHD/AEMO states it is included in fixed O&M. Efficiency is beginning-of-life round-trip efficiency. Asset life is set to 20 years for the BESS financial model based on GHD/AEMO technical life; this conflicts with the EPBC project-level operating life of 40 years from 2028 to 2068, implying battery augmentation/replacement or repowering would likely be required if the BESS operates for the full project life. Direct heat rate is not applicable for a battery. Emissions intensity is left null because operational emissions depend on charging source and accounting boundary; direct onsite combustion emissions are expected to be nil but project-specific charging emissions were not disclosed. No closure date or major refurbishment details were found beyond the EPBC decommissioning/repowering statements.
Searched project-specific sources. Official EPBC material describes Beebo as a 600 MW solar farm with a standalone 400 MW / 800 MWh BESS near Goondiwindi/Inglewood, Queensland. The user-provided and NEMStats/AEMO-derived KCI entry lists 'Beebo Battary - KCI' at 600 MW, but the more detailed official EPBC project description and contemporary industry reporting state the BESS is 400 MW / 800 MWh. Financial assumptions above are therefore estimated for a co-located 2-hour 400 MW / 800 MWh lithium-ion BESS using AEMO/GHD 2025 large-scale BESS assumptions: co-located capex = power component AUD 369/kW plus energy component AUD 290/kWh plus AUD 10 million development/land allowance. This gives AUD 147.6m + AUD 232.0m + AUD 10.0m = AUD 389.6m. Fixed O&M excludes optional extended warranty; GHD indicates an extended warranty for 20-year battery life of AUD 5,000/MW/year, which would add about AUD 2.0m/year for 400 MW. Variable O&M is included in fixed O&M. Round-trip efficiency is beginning-of-life. No reported construction contract, FID, EPC price, closure date or refurbishment plan was found. GHD default retirement cost for a 2-hour lithium-ion BESS is AUD 49,000/MW gross, implying about AUD 19.6m for 400 MW, before any project-specific site factors.
No generator-specific project capex, O&M, revenue contract, tolling contract, battery supply contract or financing announcement was found. Project configuration is source-backed from the EPBC referral as a 600 MW solar farm plus standalone 400 MW/800 MWh BESS near Inglewood/Goondiwindi. The NEMStats KCI listing found for 'Beebo Battary - KCI' shows 600 MW, but the official EPBC referral describes the BESS as 400 MW/800 MWh; this extraction uses the official EPBC battery size for battery financial estimates. Capex is estimated for the BESS scope only using CSIRO GenCost 2024-25/Aurecon 2024-25 large-scale 2-hour battery total cost basis of AUD 1,216/kW or AUD 608/kWh, applied to 400 MW/800 MWh. If the 600 MW KCI listing instead represented a 2-hour 600 MW/1,200 MWh battery, the same unit-cost method would imply AUD 729.6 million capex and AUD 8.4 million/year fixed O&M including extended warranty. Fixed O&M is estimated from Aurecon 2024 2-hour Li-ion BESS assumptions: AUD 7,000/MW-year base fixed O&M plus AUD 7,000/MW-year extended warranty, i.e. AUD 14,000/MW-year total. Variable O&M is left null because Aurecon states BESS long-term service agreements are not typically based on fixed/variable O&M. Efficiency is round-trip efficiency at beginning of life at the point of connection, not thermal efficiency. Emissions intensity is direct onsite operational emissions only; lifecycle or grid-charging emissions are not included. Asset life is based on Li-ion BESS technical/economic life of 20 years, with possible extension to about 25 years depending on condition assessment and later life extension via battery upgrades. EPBC project dates indicate an overall proposed action start date of 01/10/2028 and end date of 01/10/2068, which is longer than the default battery technical life and likely implies refurbishment/replacement for battery components if the BESS operates for the full project period.
No project-specific Beebo battery capex, O&M contract, tolling agreement, augmentation cost, or refurbishment budget was found in public sources. Financial values are estimates scaled from Aurecon/AEMO 2024-25 large-scale lithium-ion BESS assumptions for a co-located 2-hour BESS. The user-supplied KCI/NEMStats capacity is 600 MW, while multiple project-public sources for the Beebo Solar Farm and BESS report a 400 MW / 800 MWh standalone BESS. The profile capex assumes the KCI 600 MW battery is 2-hour duration, i.e. 1,200 MWh, using Aurecon's co-located 2-hour cost: AUD 471/kW power component plus AUD 314/kWh energy component, plus proportionate land/development. If the public 400 MW / 800 MWh design is used instead, estimated capex is approximately AUD 459.4 million including proportionate land/development, and fixed O&M is approximately AUD 3.2 million per year excluding extended warranties. Variable O&M is left null because Aurecon states BESS long-term service agreements are not typically fixed/variable. Direct operating emissions are treated as zero because the BESS stores electricity rather than combusting fuel; indirect emissions depend on charging source and dispatch.
